Correct answer: d) 1 and 3
Explanation:
MIG welding, also known as Metal Inert Gas welding or Gas Metal Arc Welding (GMAW), is a welding process that uses a consumable electrode and a DC power supply. Let's examine each statement in detail:
1. Consumable electrode:
- MIG welding uses a consumable electrode, which means that the electrode wire is consumed during the welding process. The electrode wire is continuously fed from a spool through the welding gun and melted to form the weld. The consumable electrode provides the filler material for the weld.
2. Nonconsumable electrode:
- This statement is incorrect. MIG welding does not use a nonconsumable electrode. Nonconsumable electrodes are typically used in Tungsten Inert Gas (TIG) welding, where a tungsten electrode is used to create an arc and a separate filler material is added to the weld.
3. DC power supply:
- This statement is correct. MIG welding requires a DC power supply. The power supply provides the electrical energy needed to create an arc between the electrode and the workpiece. The DC power supply ensures a stable and consistent welding current, which is essential for MIG welding.
4. AC power supply:
- This statement is incorrect. MIG welding does not use an AC power supply. AC power supplies are commonly used in processes like Shielded Metal Arc Welding (SMAW) or Stick welding.
In summary, the correct statements regarding the MIG welding process are that it uses a consumable electrode and a DC power supply. Therefore, the correct answer is option d) 1 and 3.
